PEP005 Gel - Biological Effects in Actinic Keratosis Assessed by Reflectance Confocal Microscopy

4. dubna 2016 aktualizováno: LEO Pharma

A Phase 1, Two-stage, Single-centre, Open Label, Within- and Between-subject Comparison Trial to Explore the Biological Effects of PEP005 (Ingenol Mebutate) Gel, 0.05%, Applied Once Daily for 2 Consecutive Days in Subjects With Actinic Keratosis on the Upper Extrem-ity. A Single-arm First Stage Followed by a Two-arm, Parallel Group, Randomized, Placebo (Vehicle) -Controlled Second Stage

This trial will be conducted to explore the biological effects in the skin following treatment with PEP005 Gel, 0.05% administered for two consecutive days, assessed by reflectance confocal microscopy.

Change in Degree of Infiltration
Časové okno: Baseline to Day 2

Change from baseline in the degree of infiltration of the epidermis by inflammatory cells following treatment with ingenol mebutate gel, 0.05% as assessed by Reflectance Confocal Microscopy (RCM) in actinic keratosis (AK) skin.This RCM imaging technique is a relatively new non-invasive, real-time evaluation method to generate horizontal skin sections at a resolution comparable to routine histology.

The degree of infiltration of the epidermis by inflammatory cells will be based on "inflammation/small bright cells" (grading 0-3) as assessed by RCM from baseline across the trial period for the subjects receiving PEP005 Gel. The degree of infiltration of the dermis by inflammatory cells will be based on "inflammatory cells in the dermis" (grading 0-3) as assessed by RCM from baseline across the trial period for the subjects receiving PEP005 Gel.
